Well, here is the log with all of the equipment attached. No simulators.
The directory to save the images is created. Ekos is saving the images. I asked it to take three 1 sec darks. I ended with 53 (several stops in between).
Ekos shows this message at the bottom:
2019-05-30T21:39:57 Restarting capture attempt #1
2019-05-30T21:39:57 Capture failed. Check INDI Control Panel for details.
2019-05-30T21:39:55 Capturing 1,000-second image...
2019-05-30T21:39:55 Restarting capture attempt #1
It seems fits viewer is not showing because Ekos fails to capture the image. But I have 53 of them.
